This might seem like a dumb question, but how do I know when it's time to rearch or replace my stock rear spring packs? I've had my '00 access cab for the last three years, and I'm assuming the leaf packs have never had anything done to them. 800lbs in the back will cause bottoming out on bumps in the road at moderate speeds. This seems softer than should be, so I'm thinking it's time to rearch, and maybe an AAL. Am I asking too much? Truck sits level when she's empty, and there's been no lift added up front.

Unfortunately, the stock tundra leaf springs are not great when you are needing to haul stuff in the bed. An AAL is notgoing to be much better either. Best thing to do is to replace the leaf pack with a set of either Deaver or Alcan leaf springs.

You can go custom and go with what I did and have a set of 63" (length i-2-i) chevy 4x4 leaf springs installed. This requires cutting and welding but, the cost to have it done was less than the cost of getting Deavers or Alcans.

Another option is to install some airbags. you can use the airbags when ever you need to haul stuff.

As far as knowing when to replace, one thing to look for is if the leaf pack starts to look like an "s". Also, you may need to replace your shocks if your rear end feels a bit bouncy.

I was wondering about the chevy swap. Actually just snagged a set. Now I just need to rope a couple of competant friends to fab brackets. Any chance at some more pics of the install?
